The perfect one step solution for creating Ice/Sliding Mazes in both Reign of Chaos and The Frozen Throne. It is the only decent system around and it even works in RoC, is lagfree, perfectly optimized, fast and reliable. The included TerrainKill feature frees you from the tedious task of creating a thousand kill-regions.

i did something similar to what you want..its worthless to try and make them move on snow...the unit was dead but yet when it go to the check point it killed all units...but noone revived...the stop at snow is VERY effective within map making and VERY useful i would recommand leaving it just the way it is

You can add a check for Triggering unit is Alive at the checkpoint to prevent that bug.

There are topics on the forum/comments on the blog about making units slide on more than one terrain type, simply add snow to the sliding system and voila.TerranKill will continue to work even if heroes are sliding on snow.
